elmslitghost,kgugala: just FYI for ice40 timing I'm pursuing patching the xml after merging since there is currently no sim.v files for v2x (although mithro has a WIP PR with them started).18:51
mithroelms: Why not just edit the XML directly?18:51
elmsmithro: Manually enter the values? I'd still like to pull the values out of the SDF using a script18:52
mithroelms: Well, initially it might be better to just do it by hand?18:53
mithroSpecially if we end up going v2x on ice40?18:55
elmsmithro: Ahh I remember now too that the timing all depends on the final target device too. So hx1k has different timing to lp1k. Next pnr uses three timing models. I think icetime has a model for each18:57
mithroelms: You could add each with a "devce=xxx" attribute and then xsltproc during the merging to filter out the ones which don't match the current device...18:58
mithroelms: Might also be worth just doing only one device first and ignoring the others18:59
elmsmithro: what is the short term goal you think I should be focused on?18:59
mithroelms: I think having *some* data getting into vtr and looking at the quality...19:00

mithroelms: We don't need arachne-pnr anywhere now, right?22:35
elmsmithro: that's my understanding22:36
mithroelms: Then lets merge https://github.com/SymbiFlow/conda-packages/pull/18 right?22:37

elmskgugala: Question about SDF parser. for multiple triples the are labeled with 'fast' and'slow'  for IOPATH, but if I understand the spec I think these are for 0->1 and 1->0 transitions. Does the xc7 sdf have a different meaning?23:12
